The Bollard Pull value, which can be interpreted as the maximum thrust that is developed for a specific amount of time by the propulsion systems of any vessel to the fullest , when it has zero speed in the forward direction, is the criterion that allows us to understand how suitable a tugboat is for a port maneuver or a towing operation.

Manoeuvring large ships at close quarters and on shallow water is one of the most difficult aspects of shiphandling because of the complex hydraulic interactions depending on the ships' speeds, on the water depth and on lateral restrictions like in canals. Training is conducted both on meeting and on overtaking ships in shallow waters. This video shows how overtaking in a canal should be conducted: come in close to the stern and then move away from the bow that will be sucked towards your...

Captain Bronson Stubbs discusses what harbor pilots do

Simulation of pilots and tugs in the Port of Brownsville from the inlet to the berth

The individual pilot operates as part of a pilotage organisation. And, as with so many things, the whole is (much) more than the sum of the parts ...

At Safehaven Marine it was great to be able to launch a new pilot boat for the Port of San Ciprian in Spain after nearly 2 months of Lockdown. She was nearly finished at the start of the lockdown. It sure was nice to be on the water again, even with social distancing.
We wanted to do something nice to lift everyone's spirits during these challenging times around the World, so we did a fly past our home Port of Cobh in Thunder Child II (Safehaven’s Transatlantic record attempt vessel) in...

off Taipei, bit choppy seas

There are some problems that never seem to go away and one is the perennial difficulties in providing a safe way of getting pilots on and off a ship.

Here’s a nice video of the ‘Independent Vision’ having her pilot embarked offshore by the Cork pilot boat ‘Failte’ an Interceptor 48 before she enters Cork Harbour. We also undertook some alongside handling trials at the same time with ‘San Cibrao’ before she is shipped to Spain. Sure was interesting trying to land the drone back on the boat in the 40kt winds offshore!
