Piping systems

Engineered to exceed classification standards, the yacht’s piping architecture is executed with precision, and there is no plastic piping in the engine room. For seawater service, copper‑nickel 90/10 pipe is specified with welded or flanged joints and threaded or flanged connections, with threaded interfaces minimized wherever possible. Sea cocks are in copper‑nickel 90/10, and every valve is ABS type‑approved for its specific duty. Where copper‑nickel lines penetrate steel decks or bulkheads, a steel sleeve approximately 350 mm in length, of larger diameter than the adjoining pipe, is fitted to safeguard integrity and longevity.

Scupper drains are fabricated in steel or aluminum with PVC piping, and stainless‑steel grates are set flush on deck; there are no sea cocks on the main deck scuppers, and all connections are hard‑plumbed. For internal scuppers, steel or aluminum threaded fittings and plastic piping are employed according to location, and the system categorically excludes hose‑and‑clamp connections.

Fuel and lube oil systems utilize steel pipe with welded or flanged joints and steel fittings, while engine‑room valves are stainless steel, true union ball type, ensuring robust, precise control.

The hydraulic installation is built around HERMETO high‑pressure seamless steel pipe with socket‑welded joints, complemented by marine‑grade hose connections sized to system pressure, HERMETO high‑pressure steel fittings, and 316L stainless steel true union ball valves for absolute reliability under load.

In the air‑conditioning plant, copper‑nickel piping serves seawater runs within the engine room, CPVC is used in the engine room for chilled‑water circuits, CPVC is continued outside the engine room, and flow is managed by CPVC or bronze ball valves.

Black and gray water lines are executed in PVC DWG (schedule 40) with solvent‑welded joints, employing steel/plastic flanged and plastic/plastic union connections, welded sch 80 steel sea cocks, and PVC true union ball valves to ensure clean, serviceable runs.

For fresh water, both hot and cold, CPVC (schedule 80) pipe is fitted and wrapped in l2 mm insulation, with solvent‑welded CPVC joints, union connections throughout, and polypropylene or CBVC true union ball valves for dependable, drip‑free service.

The bilge system draws through copper‑nickel 90/10 seawater intakes with galvanized pickups, with welded or flanged joints and threaded or flanged connections throughout; where installed, sea cocks are copper‑nickel 90/10, and valves are bronze, delivering uncompromising durability and performance in the harshest conditions.

Noise and vibration criteria

Underway, with the main engine in operation at 85% of its maximum continuous rating and one generator in operation, the yacht preserves an impressively hushed ambiance: the salon registers 65 decibels (A-weighted), the wheelhouse records 60 decibels, guest staterooms measure 62 decibels, and the owner's stateroom holds at 64 decibels. Dockside, with the main engines shut down, one generator running, and the air-conditioning operating at half speed, the serenity deepens further, with the salon at 55 decibels (A-weighted), the wheelhouse at 50 decibels, guest staterooms at 50 decibels, and the owner's stateroom at 52 decibels.

Electrical system

The yacht’s AC network is a 380/220 VAC, three‑phase plus ground, four‑wire, 50 Hz system, with power supplied by two diesel‑driven generators or from two 100‑amp sources. Each source is equipped with two seventy‑amp circuit breakers located within seven feet of the inlet, and the inputs are engineered so they cannot backfeed to one another. Power is distributed on a four‑wire arrangement, enabling single‑phase equipment to be served from one phase and the neutral at 220 VAC.

All cabling is installed in accordance with ABS rules, using thermoplastic‑coated conductors rated to 75°C in the engine room and 60°C elsewhere, fully compliant with ABS standards. High‑voltage cables are segregated from lower‑voltage runs, clearly identifiable, mounted on an approved cable support system, and provided with a continuous metallic screen, sheath, or armor effectively bonded to earth to enhance personnel safety.

Switchboards and all electrical panels are custom‑built, dead‑front, and drip‑proof, of approved regulatory construction, and arranged for ready access to all devices for replacement and service. Components—including selector switches and magnetic‑type circuit breakers—are marine‑approved, with all breakers, switches, and indicators clearly labeled by function. Wherever possible, switchboard interconnections are executed with properly sized copper bus bars. The switchboard is divided into two primary circuits—circuit number one and circuit number two.

Low‑voltage supply is equally robust. Each main engine is served by a separate bank comprising four 12‑volt batteries configured as two 8D marine‑grade 12‑volt units in series per bank, with full paralleling capability. Generator starting power is delivered by four 8D marine‑grade 12‑volt batteries, two for each generator, wired to permit paralleling. Electronics are supported by two 8D marine‑grade 12‑volt batteries wired in series, with a 24 VDC distribution panel in the Pilot House dedicated to electronics, navigation lighting, and Pilot House lighting.
