The Pilot's Advice
- Daytime. South America. Overcast. Good Visibility.
On approaching the buoyed deep water channel which led to the breakwater at the entrance to the port, I was in radio contact with the pilot launch, who reported that he was taking a pilot to a vessel anchored further out before bringing us our pilot. On receipt of this information I slowed to a speed to give bare steerage way. Eventually, however, we arrived at the buoyed channel before the pilot launch had returned to us, therefore, I altered course to proceed up the buoyed channel with still minimum power to counteract the cross-tide effect. Once the pilot boarded he ordered "Full Ahead" and moved into the centre of the channel. By this time the other vessel entering the port was close astern of us and rapidly overtaking our vessel. There then developed an intense discussion in the local language between my pilot and the pilot of the overtaking vessel as to who should pass through the breakwater first. Following this discussion my pilot advised me that as we were proceeding further up the harbor we should enter first and so we should maintain full speed. By this time the other vessel's bow was level with our stern and still overhauling us rapidly.
The situation was allowed by both pilots to develop until the bows were level. I was conning my vessel from the bridge front auxiliary tiller and could feel the intense interaction between the two vessels, I insisted to my pilot that we should reduce speed and allow the other vessel to proceed ahead of us. At this time the pilot of the other vessel stated clearly that my vessel should enter the breakwater first and that he had put his vessel on slow speed, we were then no more than 3 cables from the breakwater. The other vessel dropped rapidly astern and a dangerous situation was averted.
I think this was a case of the "Senior" pilot on the other vessel bullying the pilot on our vessel and so causing a hazardous and highly unnecessary situation.

The correct alternative to complete the sentence below is:
When the men aboard the tug receive the towing line from the ship, they _____________
Close Approach With Oil Rig
A drilling rig was engaged in operations in a designated offshore oilfield. Its location had remained unchanged for more than four months and a two-mile radius safety zone had been established. This information was adequately promulgated to mariners. Despite these measures, on a clear day, the rig's crew was alerted to a cargo vessel that was approaching with a closest point of approach (CPA) of 0.3 nautical miles. It was observed that the ship's AIS was not operational, and general calls on the VHF went unanswered.
The rig's standby vessel was then sent off to intercept the cargo vessel and after closing with her, called her by name and also sounded the danger signal of several rapid short blasts at close range. The cargo ship made no attempt to respond and continued on her dangerous course, passing about two cables off the rig despite there being unrestricted sea room to seaward of the rig.
