The salvor shall owe a duty to the owner of the vessel or of other property in danger to—
(a) carry out the salvage operation with due care;
(b) exercise due care to prevent or minimise damage to the environment in performing the duty specified in paragraph (a);
(c) seek assistance from other salvor whenever the circumstances reasonably so require; and
(d) accept the intervention of other salvors when reasonably requested to do so by the owner or master of the vessel or of other property in danger. However the amount of the reward paid to the first salvor shall not be prejudiced where the salvor proves that such a request was unreasonable.
