Support craft perform a vital role in assisting with safe operations and emergency response for liquefied gas carriers and facilities. The effectiveness of this service could be improved by a more up-to-date approach and an improved understanding of the hazards, barriers, credible scenarios, and credible response strategies.

 

The information in this book is provided primarily for organisations involved in the transportation of liquefied gas cargoes, including support craft, facilities, and ships. It may also be of assistance to regulators and government agencies. Suggested competency standards have been provided at Annex D to assist with the creation of training programmes for the crew of support craft.

This new publication from SIGTTO uses a risk assessment method and terminology to explain the environment and define some example scenarios and response strategies.

 

All of the responses contained are based on the following order of priority: protection of life, the environment, and property. Protection of life has been considered not only in the context of the ship and terminal staff involved in a cargo operation, but also to the emergency responders and the general public in the vicinity.

 

Evaluating a top event without understanding the design barriers built in to reduce risk may lead to an improbable conclusion.

 

SIGTTO is of the opinion that knowledge of the design basis for facilities and gas carriers, including typical credible (design) scenarios, may assist in the improvement of existing practice. This new publication therefore sets out to increase awareness of the philosophy behind the design, including the purpose and limitation, of equipment used. Appreciation of the credible scenarios should also assist the industry in carrying out more effective drills and exercises.

SIGTTO draws up guide for emergency support work at LNG Terminals Review by Tradewinds - June 2015
A new publication designed to give guidance to operators of tugs and other vessels working in emergency situations at LNG plants and terminals is to be made available next month.

“Support Craft at Liquefied Facilities, Principles of Emergency Response and Protection – Onshore” will be published by industry body The Society of International Gas Tanker & Terminal Operators (SIGTTO).

The new guide considers a number of typical scenarios based on what are described as “credible incidents” that may occur during the operation of an LNG carrier approaching, departing or alongside an onshore facility or a near-shore floating storage and regasification unit (FSRU).

SIGTTO says in the new document’s introduction that the effectiveness of the service provided by these support vessels could be improved by a more up-to-date approach and a better understanding of the hazards, barriers, scenarios and response strategies. The society says knowledge of the design basis for facilities and vessels may help improve existing practice.

The document details a number of what it calls “top events”, including loss of cargo containment, collision/grounding, loss of position, and intrusion. It then details the risk-assessment methodology used to explain the situation being considered and defines some examples, scenarios and response strategies.

SIGTTO general manager Andrew Clifton says the new publication has been more than two years in the making.

It has been put together by a SIGTTO working group, made up of representatives from tug-vessel operators, port authorities, ship owners, energy majors, gas companies and terminal operators under the leadership of BP Shipping’s Captain Peter Seaman.

“This publication will be of great interest to the industry and is expected to widely influence and define the utilisation of support craft in liquefied gas terminals in an emergency situation,” Clifton said.

The new guide is currently being printed and will be available to buy from the end of July.
