The Center for Offshore Safety has published Guidance on Safety and Environmental Management for System Interface Agreements.
Many incidents occur due to poor communications between two or more companies working at the same location, often on the same project or task. This document aims to establish good practices for interface management.
The following is from the Introduction to the document.
This document provides guidance for the clear definition and documentation of safety and environmental management systems expectations with example interface agreements and guidance for selection, application, and use. The guidance is meant to aid Companies and Entities in managing the interface requirements of a management system.
(A Company is An operator or contractor who intends to establish, implement, and maintain a SEMS. An Entity is an operator or contractor that performs work and/or provides facilities, services, equipment, supplies and/or information for a Company or on a Company’s asset.)
