QUEBEC, Aug. 30 /CNW Telbec/ - The president of the Corporation of the Lower St. Lawrence Pilots, Captain Simon Pelletier, took great pride today in opening the first Navigation Simulation Center at the Port of Québec. A tool at the forefront of technology, the simulator will offer users unrivalled conditions for training and improving skills in the maritime sector in Canada.

…

The acquisition of this simulator will enable the Corporation of the Lower St. Lawrence Pilots to position itself not only as a leader in terms of training and improving skills, but also as the originator of a state-of-the- art center of expertise in North America in terms of navigational safety. “We are looking forward to welcome to this exceptional training center maritime professionals from across the industry” stresses Captain Simon Pelletier.

…

In accordance with the requirements of the STCW 95 Convention of the International Maritime Organization and approved by Det Norske Veritas (DNV), the Class A simulator, Polaris, has been designed to meet the needs of training, practicing, updating and maintaining skills in subjects related to navigation, piloting, anticollision, instrumentation, maneuvering with adaptation in confined waters as well as emergency situations.

Exercises provide a highly realistic reproduction of the sound and visual environment, tidal effect and climatic factors that can occur during transit, including the effects of wind, current, heeling, shoals, loss of visibility linked to fog or rain and many other situations. Some of the simulator’s features include a visual presentation 330 degrees horizontally and 25 degrees vertically, a very wide choice of carrier ships and target ships, covering a range that is representative of the ships that sail the St. Lawrence River along with twelve complete databases making it possible to simulate nighttime and daytime maneuvers in Canada, the Unites States and Europe, and to reproduce the conditions thereof in great detail as well as recording sessions for analysis and feedback purposes.

…

The Corporation of the Lower St. Lawrence Pilots has been in existence since 1860 and has always extolled the virtues of training and updating the knowledge of pilots in order to ensure safe navigation in all sailing areas. Accordingly, the Corporation continues to run its own training and practice program for individuals who want to become pilots. It also represents its members with governments, companies and anyone involved in the maritime sector.

I’ve run into situations where it was necessary to convert decimal degrees to degrees, minutes, and seconds.

Here’s a couple of C++ functions which handle the conversion between these two formats:

std::string DegreesMinutesSeconds(double ang) ;

double DecimalDegrees(const std::string& dms) ;

These are inline functions defined in the header file, dms.h:

SAMTRA, the SA Maritime Training Academy based in Simon’s Town, recently conducted a crisis and emergency course for a group of mooring masters responsible for the mooring and unmooring of tankers at offshore installations.

This is the first course that SAMTRA has developed to cater for the offshore industry using its full mission bridge simulators, which enable participants to be exposed to a range of simulated scenarios that focus on relevant emergencies that can affect single point moorings, a multi buoy operation or ship to ship transfers.

A range of simulator exercises were conducted during the course to expose mooring masters to emergency situations which included fires, collisions, heavy or unexpected weather, evacuation of ill or injured personnel, engine, rudder and navigation equipment failures.

These exercises afforded the mooring masters the opportunity to assess their reactions to the various situations and the efficiency of their company procedures for such emergencies.

In an industry where the consequences of errors of judgment impact critically on both terminal operations and the environment, such training provides participants the opportunity of making mistakes in a simulated controlled environment without risk.

SAMTRA’s first course in July was attended by experienced mooring masters from Smit Marine South Africa.

Marine Safety International (MSI) reports that the “Gold Crew” of the U.S. Navy’s Navy’s High Speed Vessel SWIFT (HSV-2) completed five days of training at MSI Norfolk on August 5, 2005.

A significant part of the training was 28 hours of simulator exercises using MSI Norfolk’s new High Speed Vessel console. The console features separate ARPA displays for the Navigator and Officer of the Deck positions along with a shared ECDIS (Electronic Chart).

The crew training included a 24 hour Bridge Resource Management course and 16 hours of advanced shiphandling. During the advanced shiphandling phase the crew training focused on high speed choke point transits with high traffic density.

SWIFT has two crews - Gold and Blue - which alternate in manning the vessel. The Gold crew is homeported at the Naval Amphibious Base, Little Creek in Norfolk, VA. The Blue crew is homeported in at the Naval Station, Ingleside, TX.

During its last deployment, SWIFT conducted a high speed transit from Ingleside to Singapore to provide disaster relief in response to the December 2004 South Asian tsunami. The 31-knot open-ocean transit included a one-day crew swap in Pearl Harbor. Relief support operations included high speed cargo transport and over 30 days of continuous helicopter operations in support of USNS MERCY (T-AH 19)

Defence Department researchers have been trying to make people seasick—but not too seasick—so they can assess their performance under trying conditions.

Faced with shrinking rosters aboard its naval fleet and at the same time demanding more technical expertise from sailors, the military can ill afford to let rough seas compromise operations.

If commanders could identify which crew members are most susceptible to seasickness and under what conditions, they could respond by shortening shifts or replacing vulnerable sailors before they get sick.

Researchers also hope to ultimately identify what tasks can still be done even by those who are seasick, so Defence can decide where to spend its money on replacements.

The problem is, there’s no criteria for measuring seasickness, the precise conditions that cause it, or, particularly, its effect on human performance.

That’s where Jim Colwell and Scott MacKinnon come in.

Colwell, a naval architect with Defence Research and Development Canada, drafted the protocol for a study aimed at controlling illness so researchers can measure how people perform when they’re seasick.

He even came up with a Misery Scale ranging from 0 (no problems), through nine levels of discomfort, nausea, and retching, to 10 (full-scale vomiting).

MacKinnon, an ergonomist, conducted the study in a ship motion simulator at Newfoundland’s Memorial University. His first challenge was finding enough volunteers—20, in the end—willing to get sick for science.

“It’s pretty hard to get people who chronically get motion sickness to actually volunteer to do these types of trials,” said MacKinnon, whose seasick-prone wife, Helen, was among those who signed on.

“We got 20 people who at least demonstrated some levels of motion sickness. Some did end up vomiting. Some dropped out,” he noted. “Typically, it’s very hard to reel them back in once they pass a certain point.”

By altering the simulator’s motions (pitch, roll, yaw, heave, surge, and sway), MacKinnon managed to keep about half the seasick participants in the four-six range, which included sweating, dizziness, and an uneasy stomach, up to slight nausea.

All but two of the others got just seasick enough that the machine’s motions didn’t need to be altered. The two others threw up no matter what the testers did.

The results—that seasickness can be regulated for research purposes—will be published later this summer. The findings also could help industries such as fisheries and commercial shipping.

It’s not the first time motion sickness studies have been conducted, but Colwell said previous projects typically recorded how many people got sick, how fast they got sick, and how sick they got under set conditions.

“The typical kind of experiment is you set the motions at a certain level of severity and then you watch what happens to the people,” he said.

“Generally, people who begin to get motion sick progress through mild, moderate, and fairly severe symptoms over a fairly short period of time.

“So it’s really difficult to look at performance with mild motion sickness when people don’t stabilize at that level but get worse pretty rapidly.”

Colwell and MacKinnon’s study was the first to regulate the motions of the simulator by the seasickness they caused. It required participants to perform rudimentary computer tasks such as math problems and other questions.

“I wondered why anyone who knows how bad it can be would volunteer to put themselves through it,” said study participant Helen MacKinnon.

“Near the end, you got the feeling you just didn’t care, you just wanted to answer the questions. You just weren’t feeling up to it.

“I can see how anybody working on a boat would find it hard to concentrate on their job.”

In fact, the issue came to the fore after a 1997 NATO exercise where about half of 1,025 sailors surveyed aboard seven ships reported varying degrees of seasickness resulting in problems doing their jobs.
