Abstract
A method is provided for managing a master vessel change in a multi-vessel seismic system. The system includes a master vessel M and at least one slave vessel. The method includes, during at least a part of a multi-vessel operation: selecting a new master vessel M′ among the at least one slave vessel, triggered by at least one predetermined event; and transmitting, to the at least one slave vessel, at least one piece of information related to a master vessel change from the master vessel M, called old master vessel, to the new master vessel M′.
Claims17
A method for managing a master vessel change in a multi-vessel seismic survey involving a plurality of vessels and comprising a master vessel M and at least one slave vessel moving along their respective paths, the master vessel being the reference to compute proper position of said at least one slave vessel, and at least one seismic source towed by at least one vessel, said method comprising, during at least a part of a multi-vessel survey:
- selecting a new master vessel M′ among the at least one slave vessel, triggered by at least one predetermined event;
- transmitting, to said at least one slave vessel, at least one piece of information related to a master vessel change from the master vessel M, called old master vessel, to the new master vessel M′.
A non-transitory computer-readable carrier medium storing a computer program comprising program code instructions which, when executed on a computer or a processor, implement a method for managing a master vessel change in a multi-vessel seismic survey involving a plurality of vessels and comprising a master vessel M and at least one slave vessel moving along their respective paths, the master vessel being the reference to compute proper position of said at least one slave vessel, and at least one seismic source towed by at least one vessel, said method comprising, during at least a part of a multi-vessel survey :
- selecting a new master vessel M′ among the at least one slave vessel, triggered by at least one predetermined event;
- transmitting, to said at least one slave vessel, at least one piece of information related to a master vessel change from the master vessel M, called old master vessel, to the new master vessel M′.
A non-transitory computer-readable carrier medium storing a program which, when executed by a computer or a processor, causes the computer or the processor to carry out a method for managing a master vessel change in a multi-vessel seismic survey involving a plurality of vessels and comprising a master vessel M and at least one slave vessel moving along their respective paths, the master vessel being the reference to compute proper position of said at least one slave vessel, and at least one seismic source towed by at least one vessel, said method comprising, during at least a part of a multi-vessel survey:
- selecting a new master vessel M′ among the at least one slave vessel, triggered by at least one predetermined event;
- transmitting, to said at least one slave vessel, at least one piece of information related to a master vessel change from the master vessel M, called old master vessel, to the new master vessel M′.
A multi-vessel seismic system comprising a master vessel M and at least two slave vessels, said system comprising the following means configured and adapted to manage a master vessel change, which are integrated in said at least one slave vessels of the system and activated during at least a part of a multi-vessel operation:
- means configured and adapted to select a new master vessel M′ among the at least two slave vessels, triggered by at least one predetermined event;
- means configured and adapted to transmit at least one piece of information indicating that the master vessel is changing to become the new master vessel M′.
