Sea Alliance is the convoy planning practice of Kiwi Design and Engineering Limited, working from the Kwun Tong chart room at Rm H 8/F King Win Fty Bldg, 65-67 King Yip St, Kwun Tong, Hong Kong - 999077, Hong Kong (HK). We draft pilot rotations, mooring plans and berth windows for fleets that need order on the water rather than guesswork at the quay. Every convoy we lay down is a working document, tested against tide tables and crew rosters before it ever leaves the table.
Read how the six planning desks work →A convoy is never a single decision. It is six small crafts stacked in the right order, each one handing its work to the next. These are the desks that Kiwi Design and Engineering Limited keeps open through the working week, and each one feeds a specific part of the plan.
The rotation desk builds the sequence in which pilots board and leave a convoy, matching each leg to a named pilot and a realistic transfer hour. We keep a live roster so no pilot is booked twice and no swap is left to a phone call made five minutes before the boat moves. See the full manner of it on the services page.
Mooring plans are drawn before the vessel is alongside, not after. We map line runs, bollard assignments and the safe order for taking a spring on a berth that was never designed for a convoy of this size. Each draft carries a fallback arrangement in case the wind does not behave.
A berth window is the narrow slice of time when a vessel may actually occupy a quay. We plan those slices against neighbouring traffic, crane availability and the working hours of the terminal, then hand the convoy a booking it can trust rather than one it has to renegotiate at the gate.
Tide is the quiet arithmetic behind every safe arrival. Our reviewers read the tables for the exact stretch of water in use and mark the slack windows, the shallow edges and the hours when a deeper draft vessel must wait. The output is short, plain and pinned beside the plot.
Changing a crew mid convoy is a logistical puzzle of vans, flights and gangways. We build schedules that move people in orderly waves, keep handover notes on the vessel and leave enough slack in the day that a late van does not become a missed tide.
Drills are planned like any other part of the plot, with dates chosen so they do not collide with a busy berth window or a crew change. The calendar is published ahead of the quarter, reviewed monthly and adjusted when the convoy shape shifts, so the paperwork is never an afterthought.
Kiwi Design and Engineering Limited began this practice because vessels were being planned in the wrong room. Convoys were being run from spreadsheets on a sales floor, with nobody looking at a real tide table or an actual line run. Sea Alliance was set up to reverse that. Every plan we issue is drawn at a physical table in the Kwun Tong chart room, with the plot rail above, the buoy rack to the side and the tide slate within arm reach.
The work is deliberately small in scale and heavy in detail. We would rather hold six convoys a season and know each one line by line than claim a hundred and know none. That is why the six desks above are staffed by people who read charts for a living, and why the planning conversation begins with the water rather than the invoice. If you want to understand how a first convoy is laid down, start with the service overview and then open a conversation with the desk.
Our systems design background from the wider company means the plans we draft can also be carried into software when a client asks. We can turn a berth window plan into a shared schedule, a pilot rotation into a live roster and a safety calendar into a reminder set that reaches the right people at the right hour. None of that ever replaces the chart room judgement, but it does make the judgement easier to follow for everyone who is not standing at the table.
Kiwi Design and Engineering Limited opens its convoy window each Monday morning, and the plot rail takes new work until the tide slate is full for the week ahead.
