Introduction to the Anchor Handling Course

Background

A.P.Møller owns and operates a modern fleet of anchor handling vessels.

The vessels are chartered to oil companies, and rig operators; the jobs are anchor handling, tow and construction jobs.

The technical development of these ships has been fast to meet the increased demands.

The demands to the performance of the ships have been increased too.

A few hours off service can mean large economic losses for the different parties involved.

In the last years an increased focus have been on avoiding accidents, and the frequency of these accidents are low. To get the frequency even lower, actions to avoid accidents are needed. “Learning by doing”, on board an anchor handling vessels as the only mean of education, will not be accepted in the future. Part of this training process needs to be moved ashore, where crew, ship and equipment can be tested without risk in all situations.

Here we will use the anchor-handling simulator.

A study of accidents and incidents occurred on anchor handling vessels (AHV) during anchor handling operations reveals that some of the most common causes leading to incidents and/or accidents are lack of or inadequate:

•Experience

•Knowledge

•Planning

•Risk assessment

•Communication

•Teamwork

•Awareness

The keywords for addressing these causes are: “training, training and more training”

The value of on-board, hands-on training is well known and beyond any doubt but the knowledge and experience gained is sometimes paid with loss of human life or limbs, environmental pollution and/or costly damage to property.

This simulator course was developed in order to give new officers on AHV’s the possibility of acquiring the basic knowledge and skills in a “as close to the real thing as possible” environment, the only thing, however, that might get damaged is “ones own pride”.

The aims of the anchor handling course are:

•To promote safe and efficient anchor handling operations by enhancing the bridge teams knowledge of, and skills in anchor handling operations.

The objectives of the anchor handling course are:

By planning of and, in the simulator, carrying out anchor handling operations under normal conditions, the participant shall demonstrate a thorough knowledge of and basic skills in:

•Planning and risk assessment of anchor handling operations adhering to procedures and safety rules

•As conning officer carry out exercises in anchor handling operations

•As winch operator carry out exercises in anchor handling operations

•On user level, the design, general maintenance and correct safe use of anchor handling equipment

•The use of correct phraseology

The simulator course

The course consists of theoretical lessons alternating with simulator exercises.

The theoretical lessons

The theoretical lessons addresses:

•AHV deck lay-out and equipment

•AH winch (electrical and hydraulic) lay-out and function

•Anchor types, chain, wires, grapnels, etc. maintenance and use

•Planning of AH operations

•Risk assessment

•Procedures

•Safety aspects and rules

The simulator exercises

The simulator exercises consist of one familiarisation exercise and 3 to 4 AH operations. The weather condition during the exercises will be favourable and other conditions normal.

The tasks in the AH exercises are:

•Preparing the AHV for anchor handling

•Running out an anchor on a water depth of 100 to 700 meters

•Retrieving an anchor from a water depth of 100 to 700 meters

•Operating an anchor system with insert wire

During the simulator exercises the participants will man the bridge. They will be forming a bridge team, one acting as the conning officer the other as the winch operator. A captain/chief engineer will act as a consultant.

Before commencing the exercise, the participants are expected to make a thorough planning of the AH operation. They will present the plan to the instructor in the pre-operation briefing for verification.

During the exercises, the simulator operator will act and communicate as all relevant personnel e.g.:

•Deckhands – engine room

•Rig crew – crane driver – tow master

•Etc.

The instructor will monitor the progress of the exercises and evaluate the performance of the team and each individual.

Debriefing

Each exercise will be followed by a debriefing session during which the instructor and the team will discuss the progress and the outcome of the exercise.
