There are many areas where the transfer of bulk liquid cargoes and the methods used can give rise to either a short out-turn or a cargo contamination. If we consider the cargo loading and discharge cycle, a ship must first be prepared with suitably clean tanks to load the cargo; then a correct loading sequence…

Numerous groundings and near misses have occurred on ECDIS equipped ships that could have been avoided but for failures in the setup and use of ECDIS. Like most of the world’s merchant fleet trading internationally, your ship(s) is most likely equipped with an Electronic Chart System (ECS) or Electronic Chart Display and Information System (ECDIS)….
Safe practices in navigation are an important aspect of the overall safety of the ship. Perhaps more important than knowing the theory of navigation. Safe Practices are followed because of good planning and commitment by the ships leadership. In the case studies given below it shall be observed that experienced watch keepers and masters involve…
Collisions and groundings are a result of unsafe practices. Let look at the why collisions occur and how they can be prevented by implementing safe practices. Collisions in Fog The majority of collision claims seem to occur in fog or reduced visibility. Statistical analyses of these have shown that: The collision occurs during the watch…
With the emergence of satellite position fixing systems, position determination at sea today has been reduced only to plotting of latitude and longitude read from the GPS screen display. Positions so obtained have very high level of accuracy, provided the equipment is working accurately. Radar and LORAN, where available are very frequently used navigational aids…
POSITION FIXING Good navigational practice demands that the officer of the watch: ● Uses visual navigation aids and Radar to support electronic position-fixing methods, i.e. landmarks in coastal areas and celestial navigation in Ocean passage / Deep waters.● Does not become over reliant on automated navigational equipment, including electronic chart systems, thereby failing to make…
What is ISPS code? ISPS code is the International Ship and Port facility Security code. SOLAS chapter XI-2 part A and part B relates to special measures to enhance maritime security. In this context the principles behind ISPS code is similar to the ISM code on board. ISPS code emphasises the security of the persons…
What is a liner trade and how is it different from a tramp trade Liner trade is a trade where a ship is operated on one or more fixed routes with advertised and scheduled sailing. True passenger liners operating on ocean services were mostly displaced in the 1960s by jet airliners. Today, very few long-haul…
The mystery, the fear and the feeling of – “I don’t want to know” which surrounds the binnacle arises from several causes. Perhaps the greatest is simply the lack of urgency or necessity. There seems to be nothing abroad ship which makes it essential that the navigator should remove unwanted deviation. It is not even…
CHECKS PRIOR USING ECDIS FOR APPRAISAL AND PASSAGE PLANNING Following checks should be carried out by the Navigating Officer while carrying out passage planning on ECDIS: Not all sea areas are covered by ENC charts. The electronic chart coverage for the voyage must be adequate and all relevant charts must be fully corrected. For areas…
