Experts are using specialist sonar equipment to locate the black box of a Super Puma helicopter which crashed off Shetland, killing four people.
Industry representatives have agreed all Super Pumas should remain grounded.
At a meeting of key offshore operators and contractors on Monday, contingency plans were discussed.
Speaking after the meeting in Aberdeen, Oil and Gas UK Chief Executive Malcolm Webb said a number of options were being considered to transport workers while the Super Pumas are out of service.
