Technical & Training Report. April 2009
68th Technical & Training Committee Meeting : 2nd April 2009.
MarNIS project – the project officially ended in March and Nigel Allen brought along the DVD of the MarNIS concept and how things will/should change. Read the rest of this entry »
RADAR and AIS : Integrated Bridge systems Vol. 1 By Dr Andy Norris
So far as I am aware this is the first book on radar specifically written for mariners since the old Radar Observer’s Handbook, the last edition of which was produced in 1998. Read the rest of this entry »
From Paper Charts to ECDIS By Captain Harry Gale FNI
This is another timely publication published by the Nautical Institute, which provides valuable information, and advice to mariners as the traditional paper chart is replaced by ECDIS during the next few years. Read the rest of this entry »
MARNIS & POADSS
As you will be aware, the UKMPA have been involved in the European Maritime Navigation Information Services (MarNIS) project for four years and EMPA have been the project leaders for the development of the Portable Operational Approach and Decision Support System (POADSS) which developed from the Innovative Portable Pilot Assistant (IPPA) project which ran from 2000 – 2003.
Our “front man” on the POADSS project has been Southampton pilot, Nigel Allen Read the rest of this entry »

Dead Slow Ahead!!
Further to reports of high Dead Slow Ahead speeds here is one daunting copy of a pilot cord received from IMPA.
Technical & Training Report: January 2009
The Technical & Training committee met in November and this was the last meeting that Gareth Rees (Southampton) chaired before stepping down as chairman. I would like to place on record the dedication and skills that Gareth has shown and given to this committee for more than 10 years, (4 as chairman) and I hope I can match his input.

THE PIVOT POINT?
THE PIVOT POINT?
BY HUGUES CAUVIER (QUEBEC PILOT)

From the day that an officer commences his apprenticeship, the traditional introduction to ship handling instils the concept of a ship’s pivot point into the new recruit. Every navigating officer is therefore aware that a ship pivots around a point approximately 1/3 from the bow when going ahead and 1/4 from the stern when proceeding astern. This knowledge could be proudly revealed to the examiner during the “orals” examination when pushing the battered old wooden ships around books on the examiner’s table. Well, you can now forget those lessons because Canadian pilot Hugues Cauvier has studied the principles involved and the following feature seeks to explain how, in many circumstances, our traditional understanding of the pivot point is incorrect and that an equally important factor is the “Centre of Lateral Resistance” (COLR).
This concept is well illustrated by Hugues using delightfully simple demonstrations involving basic models in a paddling pool on a video stream at the following link

Introduction
The following text brings forward a new understanding of the pivot point’s position shift while handling ships. The proposed method, based on simple physical principles acting in combination, also outlines the limitation of the term “pivot” used to qualify that point. We will start from a basic rule of the thumb, which has been the traditional understanding of the pivot point until recently, and step up to more complex levels giving better explanation of the real-life behaviour of rotating ships.

PEC Abuse
PEC ABUSE
Earlier this year the Government produced the draft for a Marine Bill which, as well as introducing new legislation to cover the marine environment would also replace the 1987 Pilotage Act. Although we now understand that no Parliamentary time has been allocated for the passage of this Bill in the current legislative programme, the draft was put out to consultation and at the conference the DfT indicated that despite the probable lack of formal legislation, the DfT wished to incorporate the proposals into the Port Marine Safety Code as an interim measure pending parliamentary time for the Bill to be formally incorporated. The consultation process was therefore extremely important and I know that in addition to the UKMPA submission, many pilots submitted individual responses.
One area in particular was of deep concern to pilots and that was the inclusion within the draft of a proposal to remove the requirement for a PEC holder to be the “Bona Fide” Master or Mate of the vessel and to replace it with “any person”! Read the rest of this entry »
IMPA Report: PIANC Meeting
IMPA Report: Meeting 8 of PIANC working group 49
As the UKMPA’s IMPA representative I am involved with The Permanent International Association of Navigation Congresses (PIANC) working group 49. This group is concerned with the review of the 1997 working group 30 report titled “Approach Channels – A guide for Design”. This is the design bible used by many authorities when considering a new or modified port channel or fairway. Read the rest of this entry »
