“ Rule 15 Crossing Situation When two power-driven vessels are crossing so as to involve risk of collision, the vessel which has the other on her own starboard side shall keep out of the way and shall, if the circumstances of the case admit, avoid crossing ahead of the other vessel. Rule 16 Action by give-way vessel Every vessel which is directed to keep out of the way of another vessel shall, so far as possible, take early and substantial action to keep well clear. Rule 17 Action by stand-on vessel (a) (i) Where one of two vessels is to keep out of the way the other shall keep her course and speed. (ii) The latter vessel may however take action to avoid collision by her manoeuvre alone, as soon as it becomes apparent to her that the vessel required to keep out of the way is not taking appropriate action in compliance with these Rules. (b) When, from any cause, the vessel required to keep her course and speed finds herself so close that collision cannot be avoided by the action of the give-way vessel alone, she shall take such action as will best aid to avoid collision. (c ) A power-driven vessel which takes action in a crossing situation in accorance with sub-paragraph (a)(ii) of this Rule to avoid collision with another power-driven vessel shall, if the circumstances of the case admit, not alter course to port for a vessel on her own port side. (d) This Rule does not relieve the give-way vessel of her obligation to keep out of the way.”
“ The Defendants accept that those on board the “IRAPUA” failed to comply with Rule 5 of the Collision Regulations in failing to keep a proper lookout and that, as a consequence, … they were also in breach of Rules 7, 8, 15 and 16. They acknowledge that this was a serious fault, which contributed significantly to the collision. They accept that they should bear a substantial portion of the blame for the collision.”
“ My ships true course 246 degrees gyro course 250 degrees and sighted other collision vessel on radar scope bearing 233 degrees distance 12 miles off (local time 20.25 hrs) and visual on our portside. I seen binocular telescope that other collision vessel sighted green light also continued gave morse signal light and search light and I seen that the other collision vessel have no change their bearing. I call to the VHF but no other respond to the other collision vessel and I adjusted course 260 degrees (G) to avoiding collision. I continued call there’s no answer 6 mile off the other collision vessel. Approaching my radar detected and continued morse signal light and search light also I continued VHF call to the other collision vessel and blowed air whistle quickly with 5 short. But no respond and my radar 3 mile off checked. Later when I seen the other collision vessel continued approaching and also their heading line no change realized each other have risk of collision I ordered quartermaster hard to starboard and one short blast but collision came …. ” ii) The signed witness statement from the OOW is dated 11th May, 1991, a few days after the collision. He records that the “TOPAZ” was the first ship on which he had served as Third Officer. On the night in question, he was on the bridge with an experienced quartermaster, namely the AB, with about 20 years sea time. The key passages of this statement read as follows: “ At 2025 the vessel was steaming on true course 246 (gyro course 250) in good weather and visibility, on passage from Las Palmas to Ubu, in ballast, out ETA Ubu being 2330 hrs of the same day. At that time I sighted another vessel on radar bearing 233, distance 12 miles and also sighted her visually, with the aid of binoculars, on our port side. I saw her green light. After a few minutes I noticed that the other ship was keeping the same bearing and then realizing that she had not manoeuvred to give way I started atracting her attention by morse signaling and by searchlight, but I noticed no change in her bearing. Therefore I called her on the VHF (channel 16) several times but had no answer…. I repeated my calls on the VHF but received no reaction. As a precaution, at about 2040 hours I adjusted the course to 260 (gyro). I kept on calling on VHF with no answer until our ship was about 6 miles from the other ship which was all the time showing her green light. I continued my signals (light and morse) and also calling her on the VHF. Then, having received no response I blowed five short blows on the whistle, noticing no reaction from the other ship. At that time by radar check the distance between us was of about 3 miles and she was still continuing with no change of course. Later when I realized that the other ship was continuously approaching our ship with no change of course, I realized that we were at the risk of a collision and I ordered the quartermaster hard to starboard the rudder and gave one short blast but I could not prevent the other ship from colliding with her bow against our port side approximately at the middle of our ship…… At the time of the collision the master was not on the bridge but in the cargo control room with chief officer dealing with some ballast operation. The master had instructed me to call him to the bridge when our ship would reach 15 miles off Ubu. At the beginning of my watch the vessel was being steered by automatic pilot but when I changed the course to 260 we switched to manual steering and …[the AB]… was on the wheel. ”
“ The 3rd officer began making morse and searchlight signals to the other vessel and also to call her on the VHF. At a certain moment the 3rd officer ordered me to steer the ship manually on course 260. From my stand at the wheel I saw that the other ship was continuing to approach our ship, as before. The 3rd officer kept on making signals and calling on the VHF. There was no answer … Then the 3rd officer blew the whistle, five short signals. When the other ship was coming close to our ship the 3rd officer order rudder hard to starboard and then the other ship struck our port side amidships….”
“ Of course they enable the Court and the parties to have a broad birds-eye view of the events leading up to a collision. But their true probative value is that they may sometimes enable the Court to determine, not what may have happened, but what could not possibly have happened….”
“ ….The conduct of a prudent seaman in such circumstances is not to be tried by mathematical calculations subsequently made. A vessel will not be held at fault for keeping her course and speed, although she could have avoided collision by an alteration of either, if the other vessel by her action alone could also have avoided it. To stand on as long as it is possible to do so without immediate and manifest danger seems always to be justifiable. In The Ranza, Lord Gorall neatly epitomised the duty of the stand-on ship as being that she must wait until the other ship cannot avoid the collision and then she must act. The stand-on vessel is not to be held to blame because of the continued inaction of the give-way vessel or because the action taken by the other vessel was itself so belated as to actually aggravate the situation. But, in the end, act she must, and a vessel was held partly to blame where, being the stand-on ship and having the other’s complete lack of action plain before her for some time, she took absolutely no steps to avoid collision…. ”
